PLOW.

SPECIFICATION forming part of Letters Patent No. 630,052, dated August 1, 1899. Application filed April 3, 1899. Serial N0. 7l1,548. (No model.)

To all whom it may concern:

Be it known that I, JEssn M. HEcKMAN, a citizen of the United States, residing at Union in the county of Montgomery and State of Ohio, have invented new and useful Improvements in Plows, of which the following is a specification.

My invention relates to plows, and contemplates the provision of a disk-jointer designed more particularly for breaking plows, the said jointer being connected with a shank by a strong and durable connection and one which insures free rotation of the jointer, so as to enable it to serve the additional function of a rolling colter, and the shank being connected with the beam of a plow in such a manner as to permit of it being set at the angle of inclination best suited to the operation of the jointer, as well as raised or lowered when desired.

The invention also contemplates the provision of a jointer which is readily applicable to either a right or left hand plow, and is also readily applicable to plows having beams of wood as well as to those having beams of steel.

WVith the foregoing in view the invention will be fully understood from the following description and claims when takenin conjunction with the annexed drawings, in which- Figure l is a side elevation of a plow equipped with my improved jointer' attachment. Fig. 2 is an enlarged transverse section taken on the line 2 2 of Fig. 1. Fig. 3 is a detail plan view illustrating one of the clamps for connecting the j oint'er-shank to a plow-beam. Fig. l comprises disconnected sectional views of parts embraced in the jointer-bearing. Fig. 5 is a perspective view of a bearing-box designed to be mounted and secured on the shank. Fig. 0 is a detaillongitudinal section illustrating the clamps and the jointer-shank therein. Fig. 7. is a detail side elevation illustrating the manner in which a wood beam is adapted for the connection of my attachment. Fig. Sis a transverse section taken in the plane indicated by line 8 8 of Fig. 7.

In the saiddrawings similar letters designate corresponding parts in all of the several views, referring to which- A is a plow having a steel beam a of I form in cross-section.

B is a shank which is designed to carry a jointer, and C O are clamps through the medium of which the shank is oonnectedto the beam. The said clamps C respectively comprise a body I) or shank-holder having a groove 0 in one side adapted to receive a flange of the plow-beam, and also having a vertically-disposed apertured, set-screws 2, bearing in the body b, and bolts f, disposed at opposite sides of the aperture d and having books 9 at one end for engaging a flange of the beam at, and also having their opposite ends threaded and provided with nuts h, by which they are connected to the body cl.

As best shown in Figs. 3 and 6, the apertures (Z in the clamp-bodies or shank-holders b are circular at their middles, which are coincident with the set-screw e, and are gradually elongated from their middles to their upper and lower ends.

Clamps such as described are suceptible of ready and secure attachment to a plow-beam and are calculated to securely hold the shank against casual movement. They are also advantageous, because in virtue of the apertures d being elongated, as stated, the shank may be set at the angle of inclination from the vertical necessary to the best operation of the jointer, it being simply necessary when the shank is to be inclined to loosen the set-screws e of both clamps C andthe hook-bolts f of one of the clamps and slide the vloose clamp longitudinally of the beam and with respect to the clamp, the extent of the movement of the loose clamp depending upon the extent of inclination desired. lVhen the adjusted clamp is in the position desired, it is fixed in such position through the medium of its hook-bolts f and nuts h.

I D is my improved jointer and rolling colter. The said jointer and eolteris of concavo-convex form, with its convex side arranged adjacent to the shank l3, and it is provided with a central aperture 6 of about the proportional size illustrated. At its concave side the jointer is provided with a cone-shaped casting E. This casting E'hasa marginal flange 3' connected to the" jointer by integral'bolts 7c and nuts I, and it also has a central aperture 'm. Through this aperture 'm extends a bolt F, which has a head at at one end, designed to bear against the outside of the casting E, and threads 19 at its opposite end, and also has a spline or feather g at a point adjacent to its head for a purpose presently described.

G is a cylindrical box, which is provided with apertured lugs r and set-screws s, whereby it may be removably and adj ustably fixed on the shank B, and H is a bearing-block, which is fixed in the box by any means suitable to the purpose. The said block H, which is preferably of steel, has a longitudinal central bore t and also has cone-shaped seats u c at the ends of the bore, as shown.

I is a cone, which is designed to rest and turn in the seat to of the block H and is mounted on the bolt F and provided with a groove w to receive the spline g of said bolt, so as to turn therewith and yet be removable therefrom. J is a cone, which is threaded to en gage the threads 19 of bolt F and is designed to rest and turn in the seat 2: of the block H, and K is a nut, which is mounted on the threaded end 19 of the bolt Fand is designed to hold the parts of the bearing together and is also designed to take up wear of the parts when necessary. 1

By reason of the construction described it will be observed that the jointer D is connected with the shank B in an exceedingly strong and durable manner, all strain being removed from the bolt F. It will also be observed that the jointer is free to turn at all times and is consequently enabled to serve the additional function of a rolling colter and, furthermore, that the parts making up the bearing of the jointer may be readily adjusted to compensate for wear and may be readily disconnected for the purpose of repair and as readily assembled.

The shank B of the jointer comprises upper and lower portions B B arranged in parallel vertical planes and connected by an inclined intermediate portion 13 and hence it will be seen that by turning the upper portion B on its axis in the apertures d of the clamps O the jointer may be moved so as to present its edge or more or less of its side to the land. The jointer may also be set at various angles across the furrow by loosening the set-screws s and turning the bearing-box G on the lower portion B of the shank B.

The jointer and colter is shown as applied to a left-hand plow; but it is also applicable to right-hand plows. When it is to be applied to a right-hand plow, it is simply necessary to invert the box G on the shank B.

In order to adapt a wooden beam for the connection of the clamps O, I provide metallic plates a, such as shown in Figs. 7 and 8.

These plates are arranged above and below the wooden beam 06* and are connected therearrangement of parts, as such modifications may be made in practice as fairly fall within the scope of my invention.

Having thus described my invention, what I claim is- 1. In a combined jointer and rolling-colter attachment for plows, the combination of a shank, a bearing-box connected thereto, a block secured in the box and having a bore and cone-shaped seats at opposite ends of the same, a concavo-convex jointer and colter having a central opening receiving one end of the bearing-box, a cone-shaped casting connected to the j ointer and colter and surrounding the opening of the same, a bolt connected to said casting and extending through the bore of the block in the bearing-box, and cones secured on said bolt and arranged in the coneshaped seats of said blocks, substantially as specified.

2. The combination in aplow, of a suitable support such as a beam, a shank, a shankholder adjustably fixed on the support and having an aperture receiving the shank; the said aperture being enlarged from an intermediate point of its length to its opposite ends, and a connection between the shank and beam arranged in a different plane from the shank-holder, substantially as specified.-

3. The combination of a plow having a beam a shank comprising upper and lower portions arranged in parallel vertical planes and an intermediate inclined portion connecting the upper and lower portions, a bearing-box having eyes receiving and set-screws for fixing it on the lower portion of the shank, a combined jointer and rolling colter bearing in the box and detachably connected thereto, shankholders adj ustably fixed in different horizontal planes on the beam and having apertures receiving the upper portion of the shank; the said apertures being enlarged from intermediate points of their length to their upper and lower ends, and means for securing the shank in the shank-holders, substantially as speci fied.

4. The combination of a plow, a shank carrying a jointer, shank-holders disposed one above the other and'having apertures receiving the shank; the said apertures being gradually elongated from their middles to their upper and lower ends, means for fixing the shank in the shank-holders, and means for adjustably connecting the shank-holders to the beam of the plow, substantially as specified.

5. In an attachment for plows, the co1nbination of a shank, a jointer carried thereby and clamps arranged one above the other and respectively comprising a body receiving the shank and having a groove in one side, and a bolt adj ustably connected to the body and having a hook, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witmesses.
